Patrick Blanc, the inventor of living walls, has completed his latest vertical garden, covering the side of a five-storey Parisian block with waves of 7600 plants

Planting started in April 2013.

And this is the result in September 2013.

L’Oasis D’Aboukir (the Oasis of Aboukir) is a 25-metre-high green wall by botanist and researcher Patrick Blanc. The wall features plants from 237 different species and appears to grow up the facade in diagonal waves. It was planted in the spring and covers the previously raw concrete facade on the corner of Aboukir Street and Petits Carreaux street.

“I am very happy to contribute to the welfare and environmental consciousness of the inhabitants of a historic district in the heart of Paris,” said Blanc, who has been creating green walls for more than 30 years.

Yes lois, it must be.
However I just got an e-mail from somebody who knows a lot about vertical gardening and he says, it is not such a good idea eco wise, because of the watering through electrical systems of these garden in times of drought.
